Other Changes
=============

Arrow support
^^^^^^^^^^^^^

`Arrow <https://arrow.apache.org/>`__ is an in-memory data exchange format that is the
spiritual successor to the NumPy array interface. It provides for zero-copy access to
columnar data, which in our case is ``Image`` data.

To create an image with zero-copy shared memory from an object exporting the
arrow_c_array interface protocol::

from PIL import Image
import pyarrow as pa
arr = pa.array([0]*(5*5*4), type=pa.uint8())
im = Image.fromarrow(arr, 'RGBA', (5, 5))

Pillow images can also be converted to Arrow objects::

from PIL import Image
import pyarrow as pa
im = Image.open('hopper.jpg')
arr = pa.array(im)

Reading and writing AVIF images
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
